Question
An estimate regression equation can be judged good and reliable when ____.A. The coefficient of determination and the adjusted R squared are high B. The intercept term is not significant at a 5% significance level C. The z-test shows a rejection of the null hypothesis at a 5% significance level D. Only a and c are true E. All of the above are true An estimate regression equation can be judged good and reliable when ____.

A. The coefficient of determination and the adjusted R squared are high B. The intercept term is not significant at a 5% significance level C. The z-test shows a rejection of the null hypothesis at a 5% significance level D. Only a and c are true E. All of the above are true
Explanation / Answer
An estimate regression equation can be judged good and reliable when ____.
when the coefficient of determination and the adjusted R squared are high because r square gives the proportion of total variation in y which is explained by x and
The z-test shows a rejection of the null hypothesis at a 5% significance level
i,e. it shows that x and y are correlated.
So, option D) only a and c are true this option is correct
